Method For Forming High Hardness Hot Rolled Steel Plate

Abstract: ABSTRACT METHOD FOR FORMING HIGH HARDNESS HOT-ROLLED STEEL PLATE The present disclosure discloses a method (100) for forming high-hardness hot-rolled steel sheet. The method includes casting (102) a calcium-treated molten steel to form a steel slab (102). Further, soaking (104) the casted steel slab to a first temperature for a first period. The method includes performing an intermittent roughening rolling (106) on the steel slab until the steel slab is transformed to a transfer bar (206) that has a roughening thickness (T2), which is 1/6th of an initial thickness (T1) of the steel slab. Further, performing a continuous hot rolling 108) on the transfer bar until the transfer bar has a finishing thickness (T3) that is 1/8th of the roughening thickness and forms a steel plate. Then the steel plate is subjected to cooling (110) at first cooling rate for second period followed by coiling (112) the steel plate at second temperature to form high hardness hot-rolled steel plate.
